Re: LOB Space Reclaim Issue
I have not had your exact issue but we were able to reclaim our db by running a script located in the RemedyAndOracleCLOBS.pdf document. It details how to reclaim space and gives an oracle stored procedure you can use to change all lob storage to In-Row from Out of Row. By running the procedure our db size was reduced from 43 gig to less than 8 gig successfully. We did not run into the same issues you are having. We are on Oracle 10g patch 10.2.0.3.0 64 bit.
